DEVICE FOR SELECTING RECORDED SECTIONS OF RECORDING STRIPS Filed Sept. 13, 1957 5%aWKW /-7 TTORNE Y United States Patent 3,000,105 DEVICE FOR SELECTING RECORDED SECTIONS OF RECORDING STRIPS Frank A. Stirrup, 750 E. Front St., Plainfield, NJ Filed Sept. 13, 1957, Ser. No. 683,865 2 Claims. (Cl. 33189) This invention relates to devices for use in conjunction with elongated strips, upon which have been registered recordings of various types and kinds such, for example, as cardiograph recordings. More particularly, the inven tion deals with a device, through which strips of this type and kind can be fed and positioned with respect to spaced marking sections on the device for selecting predetermined recordings between said marked sections and then severing the strip by the device to retrieve said selected recorded section.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:

FIG. 1 is a plan view of a device made according to my invention, with part of the structure broken away and in section and diagrammatically illustrating, in part, a type of recording strip which can be employed, the strip being illustrated as protruding beyond ends of the device.

FIG. 2 is a section on the line 22 of FIG. 1; and

FIG. 3 is a partial section on the line 33 of FIG. 1 showing a modification.

In various types of recordings made on strips or sheets of material, it has been the custom to select predetermined sections of such recordings from the strip for arrangement in a record folder or mount of any type or kind in order to keep periodic records or recordings for comparision one with respect to the other.

In illustrating one adaptation and use of my invention, I have shown the device for use in conjunction with elongated ribbon paper strips 11, having square markings over the entire surface thereof, part of such markings being indicated at 12 in FIG. 1. The strip 11 in the construction shown is the type used in conjunction with the taking of cardiograph recordings. It is a common practice for a physician to select predetermined sections of such recordings for placement in a definite record folder for reference purposes.

My improved device 10 is designed to quickly and easily facilitate the selection and removal of the portions of the recordings above referred to. The device 10 comprises an elongated strip of sheet material which is fashioned to form a channel 13 defined by a back wall 14 and upstanding side walls 15, the walls 15 having,

at their outer ends, outwardly extending hook-shaped retainer flanges 16 fixedly secured to side edge portions of an elongated flexible transparent strip 17 or panel, preferably of suitable plastic material. The strip 17 extends the full length of the device 10, as do the flanges 16. It will appear from the dotted showing of FIG. 1 and the section of FIG. 2 that the back wall 18 has, adjacent one end portion of the device, an elongated fingerpiece aperture 18 to facilitate engagement with the strip 11 in feeding the strip longitudinally of the channel 13.

The sheet 17, in the construction shown in FIGS. 1 and 2, has substantially V-shaped notches 19 in one edge portion thereof, the upper edge as shown in FIG. 1, the notches extending into and overlying the channel 13, the notches being formed partially by perpendicular edges 20, the spacing of which controls the length of the portion of the strip 11 to be selected.

3,000,105 Patented Sept. 19, 1961 ICC In the use of the device, the strip 11 is fed through the channel 13 until the desired section of the strip to be selected is positioned between the edges 20; whereupon, a pointed instrument of any type or kind is positioned in the notches to form a mark on the strip 11 adjacent the spaced edges 20, after which, the strip 11 is fed through either end portion of the device to first bring one of the marks thereon in alinement with an end portion of the back wall 14, after which, finger pressure is applied to the sheet 17 and back wall 14 approximately at the position 21 at either end of the device, so as to grip the sheet 11; whereupon, the protruding portion of the strip is operated to tear the strip along the end of the device, the edge of the wall 14 being used for this purpose.

The strip 11 is then again fed to bring the second marking in the same position and the above operation is repeated; whereupon, the selected portion of the strip 11 between the markings controlled by the notches 19 will be had and this length is suitable for mounting in record folders or charts where standard lengths of the strip 11 have been maintained.

In FIG. 3 of the drawing, I have shown a slight modification of the structure shown in FIGS. 1 and 2, wherein 14 represents the back wall of a device similar to the device 10, 17' the sheet, similar to the sheet 17, and 11 indicates a portion of a strip, similar to the strip 11. With this construction, a double spring member 12 is riveted centrally, as at 23, to the back wall 14' at a position substantially in alinement with the section line 3-3 and one spring arm end portion of the member 22 is indicated at 24. This arm carries, at its free end, a punch pin 25 which is normally supported in an outwardly extended position, as indicated in dotted lines in FIG. 3 and, which can be manually operated to pass through an aperture 26 in the back wall 14', then through the strip 11' and through another aperture 27 in the sheet 17' in piercing the strip 11' and this piercing operation is performed at positions similar to the spaced notches 19 of FIG. 1.

It will, thus, be seen that the structure of FIG. 3 eliminates the need of utilizing a marking implement or instrument of any kind, as would be required with the structure shown in FIGS. 1 and 2 of the drawing.

It will be apparent that my improved device may be regarded as a channelled frame which can be composed of non-corrosive sheet metals or any other sheet material suitable for the purpose. For purposes of descrip tion, the strip 11 may be regarded as a recording element and the portion removed as a selected section of said element.

In the present disclosure showing one adaptation of my invention, the selection of sections of the strip are positioned within end portions of the frame. However, positioning of these apertures or openings can be increased in number and measured from one end of the frame to a particular opening, particularly in selection of sections of diflerent lengths and the marking means, such as diagrammatically shown in FIG. 3 of the drawing, can be arranged to register with the different openings provided.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:
